In a company specialised in collecting and sorting metals and ordinary industrial waste (paper, cardboard, plastics, wood) prior to their recycling, fire broke out around 10 am near the shear press on a pile of scrap cut. Site personnel intervened immediately with the company’s fire vehicle and hose system. The public emergency response team arrived with 3 nozzles roughly 10 min after. The blaze was extinguished within 20 min, yet fire-fighters stayed to cool the scrap until 12:30 pm in order to avoid rekindling of the fire. Extinction water collected in the concrete storage cell was conveyed to the site’s oil trap sedimentation tank before discharge into the environment. This separator was cleaned out 8 days after the accident. According to the operator, a hotspot or spark at the level of the pile of rebar being processed had ignited the hydrocarbons fouling certain metal parts. No victims or property damage was reported. The operator was required to submit to the Classified Facilities Inspectorate all appropriate receipts for oil trap cleaning, in addition to assessing ways to improve fire prevention and, when necessary, emergency intervention (sprinkling of rebar during cutting, availability of fire-fighting resources adjacent to zones prone to fire outbreak, etc.).
